AIR-CONDITIONING ,APPARATUS.

Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed December 16, 1913. Serial No. 806,981.

To all whom it may concern:

Be it known that I, Fomin BAIN, a citizen of the United States, residin at, La Grange, in the county of Cook and. tate of Illinois, have invented certain new and useful Improvements in' Air-Conditioni Apparatus, of which the following is a specification.

* My invention relates to improvements in air conditioning apparatus, to render it more sanitary, healthful and comfortable for h-reathin purposes. ."One 0% the general objects of my invention is to provide means, in association with theusual segregated steam or hot water radiator of a heatin system-for heating individual rooms,- r cleansing, heating, and humidifying the air to be breathed in such living room or apartment and to take from said room, from a point below the breathmg line, the used or vitiatedair and return it to theoutside atmosphere.

Another and more specific object of my invention is to inclose the ordinary heating radiator in a jacket or casi and to submerge moreor less of said radiator in a pan of water whereby to heat andhumidify the air, and to cleanse it by directing the course 3 section, taken on line 11.of'Fi 2. Fig. 2

is a transverse section taken on inc 2-2. of Fig. 1. Fig. 3 is an end elevation and Fig. 4 is a plan view.

My apparatus is applied} to the. ordinary radiator without the necessity of disturbing the steam connections and it. consists of a pan 5, adapted to be filled, to a greater or less extent, with Water 6,, within which the radiator 7 is located. I preferably construct the jacket or casing of two parts, consisting ot' the pan 5 and the removable portion 8, the water the pan forming an a'ir seal between the two arts. The pan 5 projects suflicl ently beyond the casing 8 at one end, to permit filling with water and a flanged ortl'OIl 9 of the casing ma overlie the ges and the other end and si es of the pan so as to substantially inclose the pan except at the end where it is to be filled.

Rising from the bottom of the jacket and projectlng up to near the top of the radiator is a bafile plate 10, and dependingfrom an upper horizontal wall 11,. are baflie plates 12 and 13. These latter plates descend toa polnt near the bottom of the radiator coils, leavmgsuflicient room for the air to pass between and under these plates. The arrows onthe left side of Fig. show the direction of the incoming air, they also show the directlon of the incoming air in Rig. 2. The upper portion of the casing 8 is connected by conduit 14 through a window board 15 with the outside atmosphere. The window board is set under the window 16 in the window casing.

An air conduit '17 for the heated air, is provided between the wall 11 and the base board 18. Upon the latter, the fans 19 and 20 and the driving motor 21 are mounted. The conduit 17 communicates with a chamber' 21 located at the left side of the fanv 19 and communicates with the eye 22 of said fan. Cold air enters the conduit 14, is drawn into the upper portion of the casin 8, and passes down beyond or below the be e plate 12 in directiontoward the water 6, and then passes upwardly, over the upper end of the bafiie plate 10, and again downwardly, under the baffle plate 13, and up again in the right side of-the casing 8 into the conduit 17, and theninto the chamber 21, communicating with-the eye 22 in the fan, and is finally discharged through the aperture 23 located in the upper part of the fan casing and directed toward the ceiling in the area to be heated. The air is thus heated and the moisture arising from the evaporated water 6, is taken up by the airwhich then becomes sufiiciently humidified, and air, having its course and humidified, and is in'the best condition for promoting health and contributing to the comfort of the occu antsof the room.

The-Hfan- 20 draws t e air from a point near the floor of the apartment into the per- 1 'forated wall 240i the casing and into the conduit'25 directly into the eye of the fan 20. It is then discharged from the fall through the conduit 26 into the open atmosphere. It will be observed, by looking at Fig. 4,.that the incoming air is taken from one direction and the air from the exhaust fan is dis-' char ed in to the atmosphere in the opposite diret on so that notwithstandin the close 'proximity of the two conduits t e air will not mix and therefore fresh air will always be drawn into the chamber continuously and vitiated or used air will be discharged into the atmosphere and givenv a direction of motion away from the point of intake. The fans 19 and 20 are practically of the same capacity so that the air pressure within the room need not necessarily be changed as substantially the same quantity of air will be exhausted from the room' that is drawn into it.

In a practical exempli fication of in vention theair contained in "an office room 15 feet square is delightfully conditioned.

by the use of a motor requiring'not more than 60 watts to operate both'fans andtherefore the continuous silent operation of the deride; and the expense thereof, is not a seiibus' objection to its use. "A'cover 27, shown in dotted lines, may be employed if necessary to, inclose both the fans and the motor. If the air of the room becomes ladened with too great a quantity of moisture it ,is only necessary toipermit the water'to be evaporated below the heated portions of the radiator to reduce the humidity of the ai'r.. The

' pipe 29 is the means for conveying steam or hot water to the radiator? and a valve 30 may be placed outside of the casing 8 and used as usual for controlling the admission of the heating medium to the radiator.

Openings 31 may be madein the bottompart of the casing 8 so that water poured into the pan 5 from outside of the casing 8 will readily pass thereinto.

While I have herein shown a single embodiment of my invention for the purpose of clear disclosure, it is" manifest that changes may be made therein, within the soope'of' the appended claims, without departing from the spirit of ,my invention. Having described my invention, what I claim is:--
